Dynavox LW6004PMR 6-1/2" Woofer
I want to make a nice set of bookshelves out of a pair of these dynavox that I bought about 10 years ago..what would be the best optimized cabinet size, whether ported or sealed?
These will work okay in either design. If they will be mated with a sub I would recommend a sealed cabinet which is .35 cubic feet with an F3 of about 88 Hz and usable room response into the 50's. If they will not be paired with a sub, the vented enclosure is 0.9 cubic feet with a 2" diameter port that is 3.5" long for a tuning frequency of 44 Hz.

What would be the best ported cabinet size for 2 of these drivers.
I have run the specs for this driver on WinISD and it gives me a 4.00 cu.ft @ 30.89Hz with two of these in box. This is a MTM set up.I bought these drivers a few years back from PE with a set of Scan-Speak tweeters (276-508) I'd really like to get them built I've never got to use them. Any help on a good build for these drivers would be appreciated.
I don't think I would try to tune that low. The F3 is only ~3 hz lower than what I came up with only using 2.5 cu ft. This should reduce the excursion on the drivers below fs and maintain some power handling as well.My recommendation is 2.5 cu ft tuned to 41.32hz and a port 4" x 5" long.

What are the correct ohm's
You show 6 ohm in the specifications. In the catalog you show 8ohm. I am interested in buying a pair if they are 8ohm. Which one is right 6 or 8?
Hello, I bought these woofers for my design and found that they are 8 ohm woofers when I verified its actual parameters using the WT3 tester which I would recommend when you purchase the drivers. This tool is extreamly helpful when getting accurate parameters for a particular design.
